Be it known that I, JAMES W. Ponen, citi- Zen of the United States, residing at Hurricane Mills, in the county ol' Humphreys and4 State of Tennessee, have invented new and useful Improvements in Pulling Implements, ot' which the following is a specification.

This invention relates to implements for pulling on wire fencing to stretch `the same, and also for stretching other articles, as vwell as for pulling stumps out of the ground.

The invention has for its object to pro- Yride a very strong and easily operated implement ot' the kind stated and to this end it consists in a novel combination and arrangement of parts to be hereinafter described und claimed.

In order that the invention may be better understood, reference is had to the accompanying drawing forming a part of this specilication, and in said drawing,

Figure 1 is an elevation oli' the implement, and Figs. 2 and 3 are enlarged cross-Sections on thelines2 2 and 3 3, respectively, of Fig. 1.

Referring specically to the drawing, 5 denotes a rack bar having teeth 6 on its opposite edges which are cngageable by pivoted 'pawls 7 carried by an oscillatory supuorting member 8 extending transversely of the rack bar and having a handle 9 connected to one of its ends. The member 8 has a longitudinal recess 10 through which the rack bar passes, and the pawls extend through said recess and are pivotedon pins 11 extending across the latter. To the rear ends of the pawls are connected springs 12 which are anchored to pins '13 extending across the recess 10, said springs serving to swing the pawls into engagement with the teeth of the rack bar.

On the member 8, midway between the pawls 7, is the pivot pin 14 thereof, on which is fulcrumed a lever 15 having one of its ends connected by oppositel extending chains 16 to the rear ends of t e pawls, so that when the lever is swung in one direction, one of the pawls is swung clear of and disengaged from the rack bar 5,A whereas a swing of the lever in the opposite` direction, disengages the other pawl.

the handle 9 is fulcrumed a hand lever 17V which is connected by a link 18 to the lever 15 for operating the latter. Any other opcrating means may be provided.

3 *ist ifcic Y 0n the rack bg'fis also mounted a slide 19, thesame eing shaped to 4fitaround the same. Thiers 'tiernas a rearward extension 20 vwhichfhae` spaced portions tting opposite sidesibflthenack bar, and through one of which the pin 14 passes, whereby a conneetinlettfenfthe slide and the memberV B fis' eneide; oonn'ectedipeI 'ilse/@pin 14', with Va spacing -washnnsa'id part and the lever 15,;andif't1e otherside is connected to the corresponding sideof the member 8 by a pivot ptn; 22 `ixtieh*is in alinement with the pin .14. Ifttherefore be seen that a pivotalonnfecti between the slide 20 and the nawl carriermember 8 is had to permit the latter to be oscillated. The sides of the slide 20 which are next to the rack bar 5 have guide 4rollers 23 which seat loosely in longitudinal'grooves 24 in the rack bar, and the pins, 14 and 22 carry similar guide rollers y p Onone side ofthe slide 19 is a laterally projectingjhook 25 and the slide also carries hauling lines vor cables 26. To the rear end of the Vrack bar 5 is connected an anchoring line or cable 27. It will be understood, of course, that chains may be used instead of cables.

IIn use, the bar 5 is anchored to a post or othernstatieary support by means of the cabl'e-27, Vand the cables 26 are connected to the part to be stretched. The p-awl carrier Suis then oscillated by means of the handle-'9, whereupon the slide20 is moved in a direction to stretch the part to which it is connected by the cables 26. For stretching wire fences, the slide 19' can be hooked to a clamp shown dotted at 28 in Fig. l, said clamp being attached to the wire strands, The device can ralso be used for pulling stumps by attaching the cables 26 to the latter.'

For returning the slide 19 to the forward end of the rack bar 5 after-the stretching or pulling operation, the pawls 7 are disengaged in alternate order, and the member 8 is operated as before. However, the member 8 must be swung to advance the aw] which is clear of the rack bar. Thus, i the pawl shown at the to of Fig. 1 is disengaged from the rack ar, the member 8 is swung to the left, which carries the pawl one or more teeth-to the left end of the rack bar, after which said p-awl is released to again engage the rack bar. The bottom pawl is now swung clear of the rack bar, and the member is swung to the right about the pivots 14 und4 22, which carries this avvl toward the leftL end of the Vrank bar or 'a distanee ef one or more teeth. The top n i mem ker Sis again"eiqivixlYL to the`left, and so on until the slide 19` as4 been returned toward the left end of the rack bar as far as desired, and the device is now again ready foi-use. v

The device is` verystrongandY durable,

Y and it. is Well adapted forheavy Work/ The fulerum ofthe awl carrier is ,close to the pawls and the evice is therefore powerful in action and Well suited4 for any stretching or pulling operation to befei'ected manuallg.

, The parts 23 and 24 providel Simple and e cient guide means for the slide 19 without making opening inthe rack bar 5 and thus weakening tliefsilflaae.V Y 1 The preferred embodiment of the invention has been shownLbut it will be evident that various changes and modifications may awl is 4now againmreleased and the be made Without a departure from the spirit and soope of the invention as claimed hereinafter.

The slide '19 is made in two parts as shown in Fig. 3 to permit ready assembly, the same being fastened together by bolts 19.

I elaim:A

A pulling implement comprising a rack bar having anchoring means, a slide shaped to iit around the rack bar end mounted for travel along the same, `said slide having spaced rearwardly extending portions between Whioh the rack bar seats, rollers carried by the slide at the inner faces thereof, the opposite sides ofthe rack bar `having longitudinal grooves in which the rollers seat, means on the slide for anchoring the same to vthe part to be pulled, pawls engageable with the `teeth of the rack bar, an oscillatory carrie-r for the pawls connected to the rear- ,Wei-diy extending portion of the slide, and operating means for the carrier.

In testimony whereof I aiiix m si nature.
